Soybean Crop Management Under Rainfed Environment
摘要
Soybean, one of the most important oilseed crop in the world, is predominantly grown in rainfed area. Optimizing soybean production in rainfed areas necessitates the judicious selection of inputs aligned with agroclimatic zones and their timely availability. Agronomic strategies specific to regions such as date of sowing, varieties, sowing in altered land configuration, use of mulching, and antitranspirants enhance rainfall use efficiency and diminish yield gaps of soybean cultivation in rainfed areas. Strategies for earlier canopy closure play a crucial role in limiting weed growth. Utilizing pre-emergence and post-emergence herbicides further reduces the risk of crop-weed competition during the initial critical stages of soybean growth. Moreover, harnessing excess rainfall through harvesting and subsequent use as supplemental irrigation emerges as a valuable approach to augment crop yields across diverse locations.
